IGNITION AND LIGHTING SWITCH.

Application filed January 12, 1920.

To all cli/10m t marg/ concern:

Be it known that I. IVILLIAM KAISLING, a citizen of the United States, and residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Ignition and Lighting Switches. of which the following is a specification.

My invention relates to electrical switches in general and has to do more particularly with so-called combination lighting and ignition switches as are used on automobiles or the like. The switch of my invention is used for controlling the lighting and igniw tion circuits of an automobile, and an ob? ject ot my invention is to produce a device of the above character which contains novel features of construction and combination o1 parts, all of which produce a simple, etlicient and economical switch structure.

A feature of my invention is the provision ot a lock of the pin-tumbler, cylinder type, which is used for locking the lighting and ignition units of the switch against actur ation. When the locking element is in one position, the switch units are free to be actuated, but when the locking element is in its alternate position, the switch units are locked against actuation. The lock is operatively associated with a sliding locking plate which is suitably supported by a mounting plate, which mounting plate also carries the other mechanism of the switch.

Another feature of my invention is the means of supporting the lock in the 1nounting plate in conjunction with the cover plate to retain said lock in position and in operative relation with the said slidalile locking plate.

The above features, as well as others, consist in the novel details of construction and combination of parts hereinafter more particularly pointed out in the ensuing` speciiications and in the appended claims.

For a more complete understanding of my invention, reference may be had to the accompanying drawings, in which like reference characters, in the several views, denote like parts, and in which Fig. 1 is a face view ot my invention;

Fig. 17 is sectional view along the line 17-17 of Fig. Li, illustrating the construction of the rotor element of one of the switch units.

Referring now in general to my invention as illustrated, it comprises a lighting switch unit L and an ignition switch unit M. The lighting switch unit L has a normal or ott position and three operative positions B, C and D. In position B the side lights of thev automobile lighting systen'i are connected in circuit; in position C the auxiliary lights are connected in circuit, and in position I) the head lights are connected in circuit; but I do not wish to be limited to this particular arrangement, as different combinations can be used without departing from the invent-ion.

The ignition switch unit M has a normal or oft position E and an operative posi tion F. in which posit-ion the ignition apparatus is rendered operative, as will be more fully hereinafter described. I also provide locking mechanism which consists preterably of a standard pin-tumbler, cylinder type lock T, which controls a sliding locking plate LP, which is adapted to lock the lighting and ignition switch units L and M against actuation. The locking mechanism til) is so arranged that it operates only when the ignition switch unit M is in its normal or off position E, but will operate to lock the lighting switch unit L in its positions A, B and C; but when in position D the lock cannot be operated. lVhen the ignition switch unit M is in its position F, the lock T can only7 be turned part way by the key. Now, if the operator attempts to operate the lock T, he is at once aware that the ignition switch unit M is in its operative or on position F or the lighting switch unit M is in its D position.

Referring now more in detail to my invention as illustrated it comprises, preferably, a mounting plate 2 made of any suitable insulating material, such as bakelite, and having studs 3 'and 4 fastened to it in any suitable manner, as by means of the nuts 5, which nuts 5 have screw-tlneaded engagement with the threaded portions of the studs 3 and 4, which extend beyond the rear face of the plate 2. The pl'ate 2 is provided with a peripheral ridge 22, extending upwardly from the plate proper. The plate is also provided with a flange upon which the cover cap of the device rests. The stud 3 is provided for the ignition switch unit M and the stud 4 is provided for the lighting switch unit L. Springs 6, 7 and S are associ'ated with the ignition switch unit M, and springs 9, 10, 11, 12 and 13 are associated with the lighting switch unit L. Springs 6, 7, 8, 9, etc., are similarly constructed so that, by describing one of them, the construction of the others is readily apparent. A tongue 14 of suitable material is provided with reduced ends 15 and 16, which form shoulders 17 and 18 upon the tongue 14. The tongue 14 is forced into a suitable opening 19 in the plate 2, which opening 19 is slightly smaller than the tongue 14, to provide a force fit; and the reduced portions 15 and 16, when the tongue 14 is in place, extend beyond the top and bottom surfaces of the mounting plate 2. The shoulders 17 and 1S protrude slightly beyond the top and bottom surfaces of the plate 2, and these protruding shoulders 17 and 1S are upset to hold the spring 6 against movement in the opening 19 in the plate 2. The spring 6 is formed out of spring metal and is provided with openings 20 in its one end, through which screws 21 pass, the said screws 21 having screw-threaded engagement with suitable tapped openings in the reduced portion 15 of the tongue 14, said screws 20 securing the said spring 6 to the tongue 14. The free end 6 of the spring 6 is provided with a rounded or curved end portion which forms a contacting end which engages its associated switch unit. The portion 16 of the tongue 14 which extends beyond the bottom surface of the plate 2 forms a connecting termin'al for the spring 6 and is provided with a saddle or clamping member 22, which provides means for securing an electrical conductor to the terminals formed by the portion 16. Screws 23 are provided with washers 24, which screws 23 have screwthreaded engagement with the clamping members 22 for securely holding the electrical conductor between the portion 16 of the tongue 14 of its associated spring 6 and the said clamping member 22.

Associated with the combination ignition switch as illustrated, I show an overload relay OR, which is used for the purposes well understood. The relay OR is secured to the supporting plate 30 in any suitable manner, -'f

'and said plate 30 is in turn secured to the studs 3 and 4 by means of the nuts 31, which nuts 31 have screw-threaded engagement with the threaded portions of the studs 3 and 4.

The lighting switch unit L and the ignin tion switch unit M are each provided with a rotor element, and as both are similar in construction, a description of one of them will suffice. The rotor element associated with the lighting switch unit L comprises a supporting stud 32, a holding disk 33 for holding the lighting switch unit L in its different positions, as will be more fully hereinafter described, washers 34 and 35, a sleeve 36 of suitable insulation material, cams 37 and 33 of suitable insulation material, a cam 39 of suitable conducting material and a washer 40, which members are all supported upon the stud 32. The disk 33 is provided with an orifice of a size to permit its being slipped over the body portion 41 of the stud 32, and when the said member 33 is in place, it rests against the shoulder portion 42 of the stud 3s. The insulation sleeve 36 is provided with an orifice of a size to permit its being slipped over the body portion 41 of the stud 32, the said sleeve 36, when in place, resting against the member 33. Tashers 34 and 35 are provided with orifices of a size to permit them being slipped over the insulation sleeve 36, and the cams 37 and 33, which are of suitable insulation material, are also provided with orifices of a size to permit their being slipped over the insulation sleeve 36. The met'allic cam 39 is also provided with an orifice of a size to permit its being slipped over the sleeve 36. The cam 39, when in place, rests between the two insulation cams 37 and 38. The washer 40 is also provided with an orifice of a size to permit its being slipped over the body portion 41 of the stud 32, and when the member 33, washers 34 and 35, cams 37, 3S and 39 and washer 40 are in place, a portion of the body 41 of the stud 32 prot-rudes slightly beyond washer 40, and this portion is upset or spun over, securing the said members upon stud 32 against displacement. To prevent the members 33,

34, 35, 37, 38, 39 and 40 from rotating about the stud 32, I provide a pin, 43, which is secured to the member 33, the said pin 43 extending through the members 37, 38 and 39 but insulated from the said member 39 by means of a sleeve of insulation 44 through which the said pin 43 extends. The member 33 is also secured to the stud 32 by means of a pin 45, the said pin 45 passing through the member 33 and the shoulder portion 42 'and the stud 32. The stud 32 is also provided with a central opening 46 of a side to receive the supporting stud 4 of the lighting switch unit L, to permit the rotation of said lighting switch unit rotor.

The insulation cams 3T and 38 are provided with wing portions 47 and 4S, and the metallic member 39 is provided with wing portions 49 and 50, which wings cooper'ate with the free ends of the springs 9, l0, ll, 12 and 13, when the lighting switch unit L is moved to its several positions, as is readily understood.

The holding member 33 is in the form of a notch or toothed disk, and to cooperate with the disks 33 and 33 to yieldingly hold the lighting' and ignition switch units L and M, respectively, in any of their operated positions, I provide a holding device H which comprises a centrally pivoted member 5l, which carries rotable rollers 52 and 53 in its bifurcated ends, said rollers 52 and 53 operating in connection with their corresponding disks 33 and 33 of the ignition switch unit M and the lighting switch unit L. The member 5l is pivotally supported at its center by a stud 54, which is suitably fastened to thel mounting plate 2 by means of a nut 55, which nut 55 has screw-threaded engagement with the threaded portion of the stud 54. A spring 56 for yielding a holding member H against the disks 33 and 33 of the switch units L and M, is provided. The free end of the spring 56 rests against the bridge of the member H, the other end of the spring 56 being fastened to the mounting plate 2 by means of a screw 57 and nut 58. lVhen one of the switch members is operated, the teeth of its disk are rotated against its associated roller, due to the action of the spring 56, and as the disc 33 advances the roller acts upon the next toothed notch so as to give a snap action to the switch member and at the same time hold the actuating members of the switch in place.

A locking arrangement is provided whereby the lighting and ignition switch units L and M may be locked in their different positions. I, therefore, provide a pinetumbler, cylinder lock T cooperating with a sliding locking plate LP. The cylinder lock comprises the usual lock case 60, which lock case is provided with the usual tumbler extension 6l, and rotably mounted in the casing 60 is the key barrel or cylinder 62. The key barrel extends rearwardly from the casing 60, and this rearwardly extending portion 62 rests in a pocket or depression 63 in the mounting plate l. The lock casing 60 is also provided with a square lug 5 64, preferably integrally formed therewith, the said lug 64 resting in a slot 65 cut in the ring portion 2 of the mounting plate 2, which ring portion 2 is formed by the inner circumferential edge of the cup-shaped portion 22 of the plate 2 and the outer circumferential edge of the plate 2. The lock barrel 62 resting in the pocket G3, which forms a seat for the said barrel G2, in conjunction with lug 64, which rests in the slot 65, centers said lock and prevents rotation of the same in the pocket 63 when the key of the lock is turned. The sliding locking plate LP, which is provided for locking the switching units L and M so that they cannot be operated, consists of a plate 7() provided with elongated slots 7l and T 2, through which the studs 3 and 4 extend. The. plate is also provided with a U-shapcd notch 73 of a size to permit it to span the lock barif rel 62 which rests in the pocket 63 in the mounting plate 2. The slots 7l and 7 2 and the U-shaped notch 73, in association with the studs 3 and 4 and the key barrel 62, form guiding means for the. plate 70, when the said plate is moved to lock or unlock the switch units L and M, as the case may be. To permit movement of the plate 70 when the key T is rotated to lock or unlock the switch units L and M, I provide apin 75, which is secured to the rearwardly extending portion 62 of the key barrel 62, the said pin 7 5 cooperating with a pin '76, which is secured to the sliding plate 70 in any suitable manner. The plate 70 is also provided with angular extensions 77 and 7S. which extensions are preferably integrally formed with the said plate 70, the said extensions 7T and 73 cooperating with the disks 33 and 33 of the switching units L and M. I have preferably arranged the nition switch unit M so that it can only be, locked in its normal or inoperative position, and I, therefore, provide a single slot 332 in the disk 33, while the disk ing switch unit L is provided with three slots 333, 334 anc 335, whereby the lighting switch unit L may be locked in its normal or two of its three operative positions. No slot is provided for the fourth operative position of the switch unit L, so that when the lighting switch unit L is in its position D and an attempt is made to lock the switch after the ignition switch unit is restored to its inoperative position, the key can only be turned part way and the operator is at once notified that the switch lever must be turned back to any of its positions A, B or C to enable him to lock the switch as is readily apparent.

of the lightlllll The disks 33 and 33 of the units L and M are provided with angular, downwardly extending arms 8O and 81, which extend into slots 82 and 83, respectively, which slots are cut in the mounting plate 2. The extremities of the respective slots 82 and 83 limit the movements of the switch units L and DI in their normal and farthest advanced positions.

In Fig. 8 I have shown the locking mechanism and operating members of the lighting and ignition switch units L and M in their normal position and unlocked; and in Fig. 9 I show the locking mechanism operated to lock the switching units L and M against movement, but also showing the mechanism at normal. To lock the switch units L and M, the key of the lock T is inserted and turned to the right until the pin 75 in the key barrel 62 engages the pin 7 6 in the plate 70. Continued rotation of the key in the lock T moves the plate 70 in an upward direction into the position shown in Fig. 9. The extensions 77 and 78 enter the slots 332 and 333 of the switching units M and L, respectively, preventing the movement of said units. To unlock the switch units L and M, the key is turned to the left until the pin 7 5 engages pin 7 6 to move the plate 7() in a downward direction, and this downward movement of the sliding locking plate 70 withdraws the extensions 77 and 78 from the slots 332 and 333.

To vieldingly hold the plate 7() in its r locked or unlocked positions, I provide a flat spring 85 secured between the member H. and the plate 2 by means of the stud 54, which holds the plate 70 in its different positions, the free end of the spring engaging the sliding plate 70. A cover or casing 90 .is provided for enclosing the mechanism, and a top or name plate 91 is also provided, said cover 90 and name plate 91 being held together in any suitable manner and being provided with suitable openings to permit the passage of the studs 3 and I. Handles 92 and 93 are secured to the studs 3 and at in any suitable manner, the said handles 92 and 93 being grasped by the operator to move the switching units L and M to their different operative positions. The cover 90 and plate 91 are also provided with a suitable opening 94e of a size to permit the passage of the forward end or head 62 of the key barrel 62, this opening 941 also forming a bearing for the head 622 of the key barrel 62 when it is rotated by the key.

From the above description, it will be seen that with the cylinder lock mounted with the rearwardly extending portion 62 of the barrel 62 resting in the pocket 63 and the lug 64C resting in the notch 65 and the barrel head 622 projecting through the opening 94: in the casing 90, the lock will be rigidly secured in place between the casing 90 and the mounting plate 2. The opening through which the head 622 of the key barrel 62 projects and the rear portion 62 of the barrel 62 which rests in the pocket 63 in the mounting pla-te 2 both serve as bearings for the barrel 62 when it is rot-ated by the key, the said pocket 63 also seating the lock in position. The shoulder 95 formed by the barrel casing 60 abuts against the inner surface of the casing 90, preventing displacement of the lock in the pocket 63, and the lug 61 resting in the notch 65 prevents the lock from rotating as a whole when the key is turned.

From the construction herein described, it will be apparent that it is unnecessary to rigidly secure the lock to any member of the switch or casing, because when the casing is secured to the plate 2 by means of the nuts 96, the loc-k will be clamped between the casing 90 and mounting plate 2.

Referring now to Figs. 11, 12 and 13, I illustrate another method of mounting the lock. In the above figures I only illustrate a fragmentary portion of the switch structure, which is the same as described in con nection with Figs. 1 to 11, inclusive, and comprises an ignition switch unit M and a lighting switch unit L in association with the sliding locking plate LP. The lock T is also of the pin tumbler cylinder type and consists of a barrel casing 60 with the tumbler extension 61 and the key barrel 622. The barrel 623 extends rearwardly from the casing 60 in a suitable shallow pocket or depression 63 in the plate 2 and is of a size to receive the rear portion 622 of the barrel 623. Tumbler' extension 61 rests in a notch 65 in the ring portion 22 of the mounting plate 2 and prevents rotation of the lock when the key is rotated. A pin T5 secured to the barrel 62 in a suitable manner cooperates with the pin 76 in the sliding locking plate T0 to move it in an upward or downward direction to lock or unlock the switch units L and M, as previously described. A cover or casing 90 is provided, as shown in dotted lines Fig. 13, with a suitable opening of a size to permit passage of the forward end or head 62 of the key barrel 622.

It will be readily apparent from the above description that with the cylinder lock mounted with the rear end 62* of the barrel 623 resting in the pocket 63 and the tumbler extension 61 resting in the notch 65 and the head 625 of the key barrel 623 projecting through the opening in the casing 90', when the said casing is in place the said lock will be rigidly secured in place between the inner face of the cover or casing 90 and the mounting' plate 2. The opening through which the head 625 of the key barrel 62?* extends to the casing 90 and the pocket 63 in which the rear end 62t of the key barrel 623 rests serve as bearings for the said barrel G23 when the key is rotated, the said pocket 63 also seating the lock. The shoulder 95 formed by the barrel casing 60 rests against the inner face of the casing 90', preventing displacement of the barrel 62s from the pocket G3, and the tumbler ex tension 61 which rests in the notch 65 prevents movement of the lock when the key is turned to lock or unlock the switching units L and lll.

Referring now to Figs 14, 15 and 16, I illustrate still another method of mounting the lock, and the switch structure, which is only fragmentarily shown, is the same as previously described and comprises an ignition switch unit M2 and a lighting switch unit L2 in association with a sliding locking plate MP2. The lock T2, in addition to the key barrel G26, casing` and tumbler extension 612 is provided with a pair of lugs 100 and 101, integrally formed with the casing 602 of the lock. The lugs 100 and 101 rest in a notch G52 in the mounting plate 2, and the rear portion of the barrel 62 of the lock rests in a suitable shallow pocket or depression 632, for purposes as previously described. A casing 002 provided with an opening through which the head of the key barrel 62G extends in association with the pocket 632 in which the key barrel rests, and the lugs 100 and 101 resting in the notch 652 of the mountingplate 2, secures the lock in place when the cover or casing is secured to the mounting plate 2, as described in connection with Figs. 11, 12 and lf3. The lock barrel is provided with the two lugs 100 and 101 so that the holes may be drilled through the lock barrel into the tumbler extension, in order that the lock tumblers and springs may be easily inserted in the holes drilled in the tumbler extension. The holes through the side of the lock barrel opposite the tumbler extension are then plugged up.

lVhile I have described various forms of my invention, it is to be understood that changes and modifications will readily suggest themselves to those skilled in the art, and, therefore, I do not wish to be limited to the exact structure as shown, but aim to cover all such changes and modifications as come within the spirit and scope of the appended claims.
